Answer:

A The postsynaptic cell is expressing different types of receptors  for the same neurotransmitter.

Explanation:

If different effects occur as a result of the same neurotransmitter acting on the same cell, it must mean that it is acting on different signalling pathways to cause a different response.

This would occur as a result of activating different receptors on the surface of the cell. While the receptors can all bind the same neurotransmitter, their actions after its binding can be different, involving different proteins and pathways.
